There are those who go on hunts. There are some who work on fortifying where we live. Personally I take the classes to be better prepared for what is thrown at us next.
No, I'm not, but that doesn't mean I don't fight. And you're referring to Sam and Dean, yeah? A lot happened to them before you came here. They just lost their brother again. Sam has a baby girl to look after. Dean has a kid to worry about as well. They can't fight every day of their lives without it being a strain.
